AI Crawler robots.txt Generator & Validator — RFC 9309 Compliant

Create custom, RFC 9309-compliant robots.txt files to manage generative AI crawlers, model training scrapers, and search engine indexers. Block aggressive scrapers (GPTBot, Google-Extended, ClaudeBot, Bytespider, CCBot, Meta-ExternalAgent) to protect proprietary content while explicitly allowing ChatGPT Search (OAI-SearchBot), Perplexity, and Applebot for search citations and traffic. Includes preconfigured presets, custom paths, sitemap directives, and an in-browser RFC 9309 simulation tester with zero server tracking.

2026 AI Crawler Standard (RFC 9309)

Protect Your Content While Maximizing AI Search Visibility

Block unauthorized model scrapers like GPTBot, Google-Extended, and Bytespider from harvesting your content for AI training, while preserving traffic citations from ChatGPT Search (OAI-SearchBot), Perplexity, and Googlebot.

About AI robots.txt Generator

ToolsWebPro AI Crawler robots.txt Generator is a free developer and webmaster tool designed to address the modern challenge of generative AI web scraping. In 2026, web publishers must navigate two conflicting needs: preventing AI companies from scraping proprietary articles and code for model training without consent, while simultaneously allowing search-oriented AI bots (like OpenAI's OAI-SearchBot, PerplexityBot, and Applebot) to index content so users can discover their websites through conversational search. By separating model training agents (GPTBot, Google-Extended, ClaudeBot) from search citation agents (OAI-SearchBot, ChatGPT-User), this generator helps you construct valid RFC 9309 robots.txt directives that protect your intellectual property while maximizing search visibility. The built-in simulator tests your rules against any path in real time before deployment. For deeper architectural explanations, read our companion [Block GPTBot but Keep ChatGPT Search Guide](/guides/block-gptbot-keep-chatgpt-search-robots-txt-2026). If you are optimizing for agentic search engines, pair your robots.txt with our [llms.txt Generator & Validator](/tools/llms-txt-generator).

ToolsWebPro provides this utility 100% free with no account creation. Our client-side tools run locally inside your browser memory so your uploaded files are never saved or transferred to third-party servers.

Frequently Asked Questions

Is AI robots.txt Generator free on ToolsWebPro?
Yes. AI robots.txt Generator is completely free to use on ToolsWebPro. No account or payment is required.
Do I need to sign up to use AI robots.txt Generator?
No signup is needed. Open the tool, paste your link or upload your file, and get results instantly in your browser.
How does AI robots.txt Generator work?
Use AI robots.txt Generator directly in your browser without software installation or registration.
Is AI robots.txt Generator safe to use?
Yes. ToolsWebPro processes many tools client-side in your browser. We do not store your personal files on our servers for those tools.
What is the difference between GPTBot and OAI-SearchBot?
GPTBot is OpenAI's web crawler used strictly to collect training datasets for foundation models (such as GPT-4 and future iterations). In contrast, OAI-SearchBot and ChatGPT-User are used exclusively by ChatGPT Search to index content, browse live URLs on behalf of users, and generate citations and clickable source links in chat answers.
How can I block OpenAI AI training while keeping ChatGPT Search citations?
Add 'User-agent: GPTBot' followed by 'Disallow: /' to block training data scraping. Then keep 'User-agent: OAI-SearchBot' and 'User-agent: ChatGPT-User' allowed (or let them inherit your standard 'User-agent: *' allow rules). This prevents OpenAI from training on your text while preserving ChatGPT search referral traffic.
Does blocking Google-Extended hurt my Google Search ranking or SEO?
No. Google explicitly documented that Google-Extended is a standalone product token used solely to manage training data for Gemini and Vertex AI generative APIs. Disallowing Google-Extended has zero negative impact on your Google Search ranking, indexing, or Google Discover eligibility.
Why should I block Bytespider and Common Crawl (CCBot)?
Bytespider (ByteDance/TikTok) and CCBot (Common Crawl) are widely cited by webmasters as being responsible for intense, high-frequency request spikes that consume excessive server CPU and bandwidth. Furthermore, Common Crawl archives are distributed publicly and ingested by dozens of third-party AI startups without direct attribution.
What is the RFC 9309 robots.txt standard and longest prefix matching?
RFC 9309 is the official IETF standard for the Robots Exclusion Protocol published in 2022. It dictates that crawlers evaluate rules by the longest matching path prefix rather than the order in which rules appear in the file. If an Allow and Disallow rule have equal match length, Allow takes precedence.
How do I allow PerplexityBot and Applebot while blocking model scrapers?
In your robots.txt, define explicit disallow blocks for training scrapers (GPTBot, Google-Extended, ClaudeBot, Bytespider, CCBot, Meta-ExternalAgent) with 'Disallow: /'. Because PerplexityBot and Applebot do not match those user-agent blocks, they inherit your generic 'User-agent: *' permissions and remain free to index your site for citations.
Where do I place my generated robots.txt file on my server or web host?
Place the file in the top-level root directory of your website domain so it is accessible at https://yourdomain.com/robots.txt (case-sensitive, all lowercase). In Next.js, place it in public/robots.txt or generate it dynamically via app/robots.ts.
Does testing or generating robots.txt upload my domain or rules to any server?
No. ToolsWebPro executes all file generation, path parsing, and RFC 9309 simulation locally in your browser using JavaScript. No URLs, domain names, or robots.txt configurations are transmitted to our servers.
